OIL-GAGE.

Specification of Letters Patent.

- Application filed February 9, 1914. Serial No. 817,643.

To all whom it may concern:

Be it known that 1, JOHN N. BA LEY, a citizen of the United States of Amerlca, re-

siding at Superior, in the county of Nuckolls and ,State of Nebraska, have invented certain new and useful Improvements in Oil- Gages, of which the following is a specification, reference bein companying drawing.

7 This invention relates to an oil gage for a crank casing of an automobile and the principal object of the same is the production of lVith these and other ob ects in View this invention consists of certain-novel combinations, constructions and arrangements of;

parts as will be hereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is an elevation of a portion of a crank casing showing the oil gage carried thereby. Fig. 2 is acentral vertical section through the oil gage. Fig. 3 is a top plan View of the oil gage. Fig. 4 is a section taken on line 44, of Fig. 2 looking in the direction of the arrow. Fig. 5 is a fragmentary sectional View of a portion of the device illustrating how the retaining screw is held-in position. Fig. 6 is a detail perspective view of a certain plug usedwith this invention.

Referring to the accompanying'dra'wings by numerals 1 designates in general a crank casing of an automobile upon which this oil gage is adapted to be used. The oil gage comprises .a plurality ofheads which'are formed similarly to each other so as to be interchangeable if desired and so. as to be cast by a single mold. Each head comprises a body 2 having an enlarged shallow pocket 3 communicating with a comparatively deep socket 4. A hollow glass tube5 is adapted to fit in the pocket 3 of each head so as to overhang the socket 4. Each headis also provided with an internally threaded passage 6 communicating with the socket 4. When the glass tube 5 is in position it will overhang the socket 4 and be positioned in alinement with the threaded passages 6. A

retaining screw 7 comprising an elongated g had therein to the ac straight body is passed through the passages 6, sockets 4, and pockets 3 and is provided at one end with the threaded portion 8. for engaging one of the threaded passages 6. The opposite end of the retaining screw 7 is provided with a head 9 bearing upon a washer 10 for efliciently closing the passage 6 adjacent this portion of the screw. It will be seen that by rotatingthe screw 7 by means of the head 9, the body 2 will be drawn into firm engagement with the end portions ofthe glass tube 5. A packing gasket 11 is positioned' upon each end of the glass tube 5 so as to be in position within the pocket 3 of each body 2. These gaskets 11 are. com-- pressed, since they are formed of rubber or similar material, by the placingof the ends of the'tube within the pockets 3 and therefore the gaskets will bind upon the tube and within the pockets, thereby eficiently closing the end portions of the glass tube 5 and preventing the oil from leaking. In order to attach this device to the casing 1, each body 2 is provided with a transverse threaded 7 opening 12 which receives the threaded end '13 of the connecting pipe 14. Each pipe 14 is provided at its outer threaded end 15 with a threaded collar 16' adapted to engage the short pipes 17 carried by the casing 1. By the use of these .collars 16 it will be seen that the pipes 14 will be held in firm engagement with the short pipe 17, thereby retaining the oil gage in itscorrect position for determin' 'ing the amount of oil within the casing 1.

Each body 2 is also provided with a transverse internally threaded. bore 18 formed in alinement with the threaded openings 12, these bores 18 being adapted to receive the cockslt). By forming the heads in this construction it will be seen that the same may be interchangeably mounted upon the glass tube 5, whereby when the device is cleaned it will not be necessary to place a particular head-upon one end and another particular head upon the opposite end but either head may be placed in position and held in engagement with the glass tube 5 by means of the screw 7.

From the foregoing description it will be seen that since the device is held in an assembled position .by means of the retaining screw 7, the device may be easily disassembled by the removal of the screw 7 It Patented Sept. 15, 1914.

will also be noted that a screw plug 20'hav- T "ing a transverse slot 21 is adapted to be threaded into engagement with one of the threaded-passages 6 for preventing the escaping of oil therethrough.

From the foregoing-description will be seen that a simple and efficient oil'gage has been produced which will allow the amount of oil within the casing to be easily-deterthe upper tube 14, thereby preventing the gage from becoming air logged. 4

Having thus described the invention what is claimed as new, is

An oil gage of the class described comprising a pair of heads, each head provided with a shallow pocket andwith a reduced comparatively deep socket communicatin with said pocket, said head also provide with a threaded passage extending therethrough and communicating with one end I of said socket, said head also provided with an alined threaded opening and threaded bore, a glass tube having its ends extending into said shallow pockets, the side portions of said tube being positioned at a spaced distance from the side portions of the pocket,

compressible gaskets positioned within said pockets and binding upon the side portions of thepockets and the outer portions of the tube, a screw passing through said tube and said heads and detachably engagin one of said threadedpassages whereby te gage will be held in an assembled position, and feed pipes and drain cups carried by said threaded openings and threaded bores. :In testimony whereof I hereunto afiix my signature in presence of two witnesses.
